整体错齿三面刃铣刀齿槽较浅,齿槽角较大。在制造这种铣刀时,可将多个刀坯串在一起,按螺旋齿加工,既能保证质量,又大大提高了生产效率。具体的加工方法如下。同一规格的整体错齿三面刃铣刀的刀坯车好之后,插出键槽。然后将多片铣刀刀坯串在带键的心轴上。在X62W铣床上将其视作螺旋齿平面铣刀加工。先是隔—齿铣—齿(即每铣—齿分度头转(360°×2)/Z,式中Z为铣刀的全齿数),见图1所示。
The whole wrong tooth milling cutter on three sides shallow, tooth angle larger. In the manufacture of such cutters, the multiple blanks can be string together, according to helical tooth processing, both to ensure quality, but also greatly improve the production efficiency. Specific processing methods are as follows. The same specifications of the overall wrong tooth three-sided cutter knife blanks a good car, insert the keyway. Then the multi-blade milling cutter blanks on the mandrel with key. In the X62W milling machine, it is treated as helical tooth surface milling cutter. First interval - tooth milling - tooth (ie per milling - tooth indexing head turn (360 ° × 2) / Z, where Z is the full number of milling cutter), shown in Figure 1.
